When I configured my new firewalls to register with my panorama, they didn't appear. I checked the following points: - Connectivity between my firewalls and my Panorama : OK => I do some packet captures on both side - TCP bidirectional traffic on port 3978 : OK => I do some packet captures on both side - Re-generate SSL certificates on my Panorama : OK => On my Panorama web gui, I see my certificate marked as valid. - Copy-paste serial number from my firewall to my Panorama : OK - Allow IP of my firewall on my Panorama's managment interface : OK => I configured it - PAN-OS version on my both equipment : OK => we are in 6.1.8 - Reduce MTU size : OK => MTU = 1300 on my firewall because we pass into VPN tunnel to contact my Panorama. - NTP synchronization : OK => Both equipments are on time. I checked these topic: https://live.paloaltonetworks.com/t5/Management-Articles/Troubleshooting-Panorama-Connectivity/ta-p/54224 https://live.paloaltonetworks.com/t5/Management-Articles/Connectivity-Issues-with-Panorama/ta-p/56445
If anyone has got this issue, I'll be happy to know the resolution.
Have a nice day.
